At Boise's zoo, Zoo Boise. Zoo Boise is very different from Pocatello Zoo. Zoo Boise appears well-funded and is park-like and has lots of visitors. It charges $5 admission fee for an adult. Pocatello Zoo doesn't appear to have much funding, but feels totally magical. Its landscape is mostly natural and its animals are mostly native, both captive and free. Pocatello Zoo charged $2.25 admission last time I went in there a few months ago, and has relatively few visitors.
